Mayor Jerry Sanders has proposed restoring even more city services — from adding library hours to filling potholes to hiring public-safety workers — as San Diego’s tax revenues continue to surpass expectations.

The mayor wants to add $12.2 million more to the spending increases he announced last month when he released the initial $1.15 billion 2013-14 budget.

He is now calling for additional operating hours for branch libraries that will keep them open 44 hours each week, up from 36 earlier this year; increasing the number of recruits in the city’s four annual police academies from 25 to 30; creating a second firefighter recruiting class of 30 hires; and boosting money for infrastructure projects ($8.3 million).

Sanders also used Wednesday’s announcement as an opportunity to criticize City Councilman Carl DeMaio, who is running to succeed the termed-out Sanders. The called the service restorations the result of years of difficult decisions he and the City Council have made in recent years.

“Not everyone, of course, has participated in these important undertakings,” Sanders said. “Some members of council just sit back and watch, offering only criticism, not wanting to make tough decisions that might hurt their political careers. … The rest of our city put the taxpayers first. Together we’ve reformed city government in ways that have never been done, but our work’s not over. Reforms will continue … and we’ll continue to restore more services.”

Asked to clarify his comments about DeMaio, Sanders said: “I’m not a candidate for anything so I don’t have to make up things. I don’t have to be on a political doomsday tour to make people think it’s worse than it actually is. … I want to be very clear that one council member has to have doom and gloom in order to get elected to mayor, but I’m not buying into that and I don’t think the people in San Diego are either.”

DeMaio criticized Sanders and others last month for trying to paint a rosy future for San Diego when the mayor said rising revenues allowed him to restore services that had been cut in recent years. DeMaio said the mayor was ignoring the still low service levels and nearly $900 million backlog in unfunded projects for streets, buildings and storm drains.

Annual pension costs are projected to grow in the near future to pay off a $2.2 billion deficit.

DeMaio released a statement Wednesday responding to Sanders.

“It’s silly season. Chalk it up to that,” he said. “I don’t care about credit, I’m just thrilled our fiscal reform agenda is working for taxpayers. We all can celebrate and be proud of that we have made this much progress without a tax increase. I look forward to finishing the job of fiscal reform as San Diego’s next mayor and presenting a budget in December that fully funds our road repairs and restores more neighborhood services.”
